SOURCE: Where is the knock sensor located on a 2.5 Subaru outback 1998?

directly below the throttle body on the drivers side of the engine block. Has a white connector attached to a single black wire lead. I had to remove the black plastic piece that connects to the throttle body and the air filter housing, in order to see/get at it. Easy fix once you find it. Haynes manual shows it in a different location, so don't confuse yourself looking at the diagram.

SOURCE: where is the coolant sensor located?

The Coolant Temperature Sensor is located under hood, center, front engine area, below valve cover, mounted next to water outlet Under hood, center, front engine area, below valve cover, mounted next to water outlet.

REMOVAL & INSTALLATION CAUTION Use extreme care if removing a sender from a vehicle which has been driven recently. The coolant could be extremely hot.

  1. Disconnect the negative battery cable.
  2. Access the thermometer on the intake manifold (1.2L engine), radiator (1.6L, 1.8L, 2.7L engines), or coolant pipe (2.2L, 2.5L and 3.3L engines) and unfasten the wire harness attached.
  3. Loosen the draincock at the lower portion of the radiator and drain enough coolant into a suitable container to bring the level below the thermometer.
  4. Loosen and remove the thermometer. Inspect the threads of the manifold, radiator or pipe, and use a thread chaser to restore the threads if damaged.
  5. If reinstalling the original thermometer, remove sealing gasket and replace with a new one.

To install:
  1. Position thermometer, and new sealing gasket into hole in manifold, radiator or coolant pipe, depending on model, and hand-tighten.
  2. Using an appropriate socket, tighten the thermometer to 2-3 ft. lbs. (3-4 Nm).
  3. Connect the wire harness to the thermometer. Tighten the radiator draincock, if not already done.
  4. Connect the negative battery cable.
  5. Fill the cooling system with coolant and bleed.

Good luck, and remember rated my help.

SOURCE: subaru wrx impreza showing fault code p0037. how

It's an O2 sensor according to the above link, and it is bank 1 sensor 2 low, the 2 meaning that it is downstream past the catalytic converter but not on the manifold.

- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Faulty Engine Control Module (ECM) Possible Solution Tech Notes The code means that there is a problem with the heater element circuit of the heated oxygen sensor. Water getting inside the heated oxygen sensor connector can caused the heated oxygen sensor fuse to blow, which is a very common problem for this type codes. Before replacing the sensor, check for the condition of the heated oxygen sensor fuse and connectors.
Good luck on this repair.

    Does 88 omni have a cold sensor

    There is a throttle body temperature sensor, 2 wire. There is a 4 wire idle control motor. Check both of them. There is also a throttle position sensor with I think 3 wires. If first two don't help, check the TPS. Check and clean out the air passages that the idle control motor attaches to and controls.

    A THROTTLE POSITION SENSOR (TPS) is usually located on the butterfly spindle so that it can directly monitor the position of the throttle valve butterfly.
    Throttle actuator control(TAC), that code comes from that part of the system too.

    1995 subaru legacy at 1 on the rpm gauge moving or in park it wants to stall out after it go pasts 1 it will drive okay.. but before it will wanna kept cutting out

    it might be a bad TPS (throttle position sensor). it operates similarly to a volume control knob on a radio. as you accelerate the butterfly on the throttle body opens to allow more air into the engine, as you would turn up the volume on the radio. there could be "flat spot" on the sensor. they can be checked with a scan tool with real time display. if the sensor is bad it needs to be replaced.

    What is the sensor on the front of the throttle body on a 99 grand am

    Its either a mass air flow sensor or a throttle position sensor(TPS) if it is on the side of the throttle body in-line with the butterfly it is a TPS. If it is inside the air intake tube it is a MAF sensor but those are usually either in the intake after the throttle body or in the intake tube right after the air filter

    Throttle Problems

    Go to an autoparts store like autozone or advance (also check out their websites). Some stores can test the throttle position sensor so that you will know if it is the problem or not. No sense guessing or replacing something that doesn't need replacing. Just because the TPS is only a year old doesn't mean it can't be faulty. Hope this helps and best wishes.

    98 lexus gs300 codes p1120 p1121

    I wanted to start a thread specifically about failures within the throttle body concerning the GS300 (1998 in my case)

    My symptons were:
    VSC, VSC OFF, and ENGINE Lights would come on, followed by my car going into Limp Mode, where only that last 25% (if that) of the throttle would respond (basically have to floor the pedal to even move at all).

    During the mornings, or when the engine was COLD, the throttle operated normal...then once the car warmed up, usually at about 10 mins, the problem would happened intermitantly at first...1 or 2 days over the course of a week, then it became more consitent, until last week it became a daily problem.

    The first part I tried was the Throttle Position sensor, which is on the front side of the throttle body, and the easiest thing to replace...this didnt help at all. $300 part from Lexus, $80 part from (exacly same part toyota OEM)

    "Idle Valve Motor", which is the larger electrical object next to the TPS on my 98 GS300. Problem is solved.

    The Codes I got were P1120 and P1121 - Accelerator Sensor problem. However it wasnt really the Accelerator Sensor, it was indeed to actual electrical Motor that controls the opening of the Butterfly valve inside the Throttle body.

    I found the problem by good old trouble shooting, and using an ohm meter to see if the throttle electric motor was getting elev, I found that the elec motor just to the left of the TPS was basically freaking out and shutting down. The Accelerator Pedal Sensor is on the Back-side of the throttle body where the throttle cable connects to, and has a spring on it. It was fine.

    GS300's are indeed "drive by wire" concerning the throttle...the cable triggers the Accel Pedal Sensor, which sends a signal to the ECU, the ECU then sends power to the Idel Valve Elec Motor (next to the TPS), which opens and closes the mechanical butterfly valve, then the TPS sensor detects how far the elec motor is actually opening the butterfly valve...its a closed-loop feed-back system, meaning any failure in any sensor will cause the entire systm to fail.

    The throttle cable apparently is ONLY there to allow the fail-safe of having that last 10-25% throttle when the electronic system fails...there is a gearbox inside the throtle body which allows the tail end of the throttle to manually engage the butterfly valve...the rest of the time, the butterfly valve is 100% opened and closed via the idle control motor.
